Summary
SQLFluff: Uncontrolled Resource Consumption in SQLFluff Parser
Details

Impact

In deployments where untrusted users can provide SQL queries to be linted, an untrusted user can submit a malicious long query to any application using the parser to trigger a Denial of Service through resource exhaustion.

Patches

Versions 4.2.0 and up contain a configurable parse node limit, which is enabled by default, to prevent this manner of exploit.
